Table 1 A summary of HDR-derived gene-editing on RAG2 locus. This is a summary of three independent replicates. A total of 154 embryos were injected and 28 embryos reached blastocysts on d 7. From 23 blastocysts genotyped, two embryos presented homozygous HDR-derived alleles (8.69%) and seven embryos carried heterozygous HDR-derived alleles (30.4%)
